You'd be better off reading the entire file into the buffer and then
manipulating the string before writing the result back to the file.

Functional example:

<?php
$buffer = file_get_contents($file);
$buffer = str_replace("param3=","param3=2323",$buffer);
$fp = fopen($file,"w");
fwrite($fp,$buffer);
fclose($fp);
?>
